Abstract: ABSTRACT       A nozzle for fitment to hand actuated liquid pumps having a barrel portion with a bore therethrough for passage of a liquid is disclosed.  The nozzle features an integrally formed nozzle cap which is mounted to the barrel and which encloses an integrally formed sealing structure.  The sealing structure provides a peripheral seal to provide a liquid-tight seal around the barrel between the nozzle cap and the barrel.  The sealing structure also provides a check valve portion which is movably-positioned at the mouth of the bore.  The check valve is biased to form a liquid-tight bore seal.  This bore seal is overcome by liquid pressure which builds in the bore upon actuation of the pump.  Also provided is a spray means which is fittable within the nozzle cap and which is in abutment with the end wall of the nozzle cap.  The spray means, along with the wall of the nozzle cap which it abuts, form a path for the liquid as it is dispensed, which path will cause the liquid to break up and form a spray pattern.

Abstract: Abstract The invention is a new family of phosphine compounds which can be used to make optically active metal coordination complex catalysts which combine high efficiency with a capability of performing rapidly (high efficiency and rapidly being established from Tables I, II and III as being greater than 75% efficiency and in times of not more than a few hours, preferably less than one hour) in water and thus avoiding solvent recovery and loss problems.  The catalysts can be used in some alcoholic mediums as well as in some aqueous mediums. These catalysts are useful in catalytic asymmetric hydrogenation of some olefinic compounds.  The new phosphine compounds are made from novel phosphine oxides.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to smoking articles having reduced free burn time, including cigarettes, cigars and little cigars.  The smoking article comprises tobacco wrapped in a paper having at least one circumferential band printed between the ends of the smoking article; preferably at about the center of the smoking article.  The band contains a substance which will cause the smoking article to extinguish in about 2-5 minutes under free burn conditions after the cone reaches the banded area if it is not puffed.  The band is typically about 2-10 mm wide containing a substance which is a liquid in the temperature range of about 100°C to 200°C and which as the burning cone comes in contact with it pro-vides a fluid film on the paper, without substantially pene-trating through the surface of the paper, which film is sub-stantially impervious to air and decomposes and/or distills endothermically from about 140°C to 300°C to yield gaseous decomposition products normally present in the smoke of smoking articles without the band.  The amount of the substance used in the band should be sufficient to extin-guish the smoking articles under free burn conditions within 2-5 minutes.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for incorporating one or more additives throughout an expanded food product. An expandable mixture of moistened farinaceous and/or proteinaceous materials is extruded at elevated temperatures and pressures through the die orifice of an expander-cooker into the cylindrical bore of a tubular extrusion die which is secured to the external face of the extruder die plate.  The cylindrical bore of the tubular die has the same cross-sectional area and shape as the die orifice of the extruder, so that as the mixture passes longitudinally through the tubular die it is still radially confined and is maintained at the same high pressure and temperature as when extruded through the die orifice.  One or more liquid additives are injected under pressure into the body of the farinaceous and/ or proteinaceous mixture as it is passed through the tubular die, through a nozzle mounted concentrically within the cylindrical bore of the tubular die.  As the material is extruded from the tubular die into the atmosphere, it expands to form a porous structure.  Simultaneously with the expansion of the mixture, the liquid additive diffuses throughout the porous structure, from the center to the exterior surfaces thereof, to thereby provide a porous expanded product in which the additive is incorporated throughout the product.

Abstract: ABSTRACT OF THE DISCLOSURE     In the heat treatment of aluminium alloy strip, in which hardening of the material is effected by heat treatment to dissolve pre-existing precipitates in the metal matrix followed by quenching and ageing, the electrical conductance of the strip after quenching is measured using a conductivity probe scanned across the width of the strip, the heating being controlled in accordance with the measured conductance so as to obtain uniform electrical conductance across the width of the strip.  This measured electrical conductance has a close correlation with the required mechanical properties.  A transmitter producing an electromagnetic field is moved across the strip and a receiver, picking up signals due to the eddy currents in the strip, provides an output automatically controlling the movement of flux modifiers of a transverse flux induction heater to control the strip heating.
